To @ZZ whom t may Concern:

Be it known that l, SAMUEL F. QAY, a citizen of the United States, and resident ol Flagstaff, in the county of' Coconi'no and State of' Arizona, have invented certain new and useful Improvements in Conveyer Cleats or Flights; and l' do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make land use the same.

'My invention relates to an improved flight or cleat for conveyers of the chain type. It is one of the objects of iny invention to provide a light' or cleat which has a lower member of substantially the width of the trougt in which the chain runs. and an uper member coperating therewith in such a .manner that the flight or cleat is easily assembled or disassembled, and is yet securely fastened in place whenitis assembled.

Another object of my invention is the provision of a flight or cleat of the abovementioned type of which the members are fastened together without the use of a bolt or rivet.

Still another object Ioil-my invention is the.

provisi'ii'of a flight" or cleat comprising a lower member provided with a link-receivf ing 4groove in one side intermediate its ends and having the opposite side cut out to a horizontal plane to a point substantially above said groove and thus curvedupwardly in a 90 degree arc, the upper member being so shaped that it coperates with thelcut-out in the lowermemberin such a manner that it may be placed against the link and rotated in a seated position without resistance.

A still further object is the provision in a flight or cleat of this type of tongue and cotterfpin means for securing the members comprising the flight or cleat together.

Referring to the drawings annexed hereto, and in which I have illustrated a preferred embodiment of my invention: Figure 1 illustrates in perspective the upper member of the flight or cleat. Fig. 2 illustrates in perspective the lower member of the liight or cleat. Fig. 3' is an elevationviw-ef@the upper and lower members in position Onthe link of a chain to be assembled. Fig. 4 is a view similar to Fig. 3 but showing. the upper member partially rtated into the position. Fig. 5 is a view similar to Figs. 3

and e, but kshowing the upper member wholly rotated into its seated position, and secured4 the lower member 1 illustrated in Fig. 2 is of` length'substantiallythe width of the trough in 4which the conveyer runs, as illustrated best in F 1g. 6. The lower side 2 of this lower member is provided intermediate of its ends' with a link-receiving groove 3, whereas the upper side is cut away on a horizontal planel to a point substantially above the center of the groove 3, and 1s then cut away to form a surface representing au arc of 90 degrees.

At the outer end of this lower member 1 is' formed a boss 4 having a curved tonguefre ceiving recess 5 and a transverse pin hole 6.l At the edge 7 of the curved portion -of the upper side is a recess 8.

. The upper member 9 is of a length to fit A in the cut-away portion of the lowerl member, and in its upper side has a link-receiving groove 10. The lowerl side thereof is shaped at its inner end as shown at 1,1 to lit upon that portion of thevsurface of the cut- .,away portion of the member 1 representing a 90 degree arc, while the rest of the lower surface ofthe member 9 is shaped to seat against the horizontal cut-away portion.

The member 9 has on its lower face a spur- 12 which, as will be seen by referring to Figs. a and 5, when the upper member is in the seated position engagesthe recess 8 in the lower member and prevents lateral displacement of the upper and lower members with respectto eachother, and also receives the shearing stresses which may be exerted upon the fastening means during the operation of the conveyer.

The fastening means comprises a tongue 13 integral with the upper member 9 and which, when the upper member is rotated to its seatetl'positioin enters the receiving recess 5 inthe boss il. rilhe tongue 13 is provided with a pin hole 15 which, when the tongue is in the recess 5', alines with the lpin hole 6. 1n order to hold this tongue in` the recess, and thereby lock the upper and lower members together, a split Cotterpin 16V is insertedin the pinhole 6 land extends through the pin holeli inthe tongue 13, its free ends beirg bent apart,

inserted in the link until the link-receiving groove 3 engages the link and the lower member drops into place. The upper member is then placed against the upper part of the link, in the position shown in F ig. 3, and is rotated in the direction indicated by the arrows in Figs. 3 and 4 to a position where it seats against the cut-away portion of the'lower 1ne1nber,'or to that position shown in Fig. 5. The split Cotter-pin 16 is then inserted and the ends bent apart as shown.

In order to remove the flight or cleat, it is only'necessary to withdraw the Cotter-pin 16 and rotate the upper member 9 in a direction opposite to that which seats it in place.

In order to reinforce the lower and upper members, that portion of each member containing the link-receiving groove is made of heavier stock than the rest. Also the lower member may be provided forcing ribs such as 17.

While I have herein shown and described one specific embodiment of my invention, it is to be; understood that I do not Wish to be limited thereto except for such limitations as my claims import.

I claim:

l. The combination With a conveyer chain', of a Hight comprising a lower member having a link-receivinggroove, a boss integral therewith and having a curved tonguereceiving recess, an upper member seating' on said lower member and having a link? receiving groove coperating with said rstmentioned groove to. retain said flight or with reincleatin a link, a tongue integral with said upper member and entering said tonguereceiving recess to hold said members in position, and means for securing said tongue in said recess, substantially as described.

2. The`combination with a conveyer chain, of a flight comprising a lower member having a link-receivin g groove in one side intermediate its ends and the opposite side thereof cut out on a horizontal plane to a point substantially above said groove and thence curved upwardly in a 90 degree arc, a boss integral with said lower part and a tongue-receiving recess therein, an upper part provided on its upper side with a linkreceiving'groove for coperation with said first-mentioned groove to retain said flight or cleat in a link and having its lower side shaped to seat against the cut-out or said lower member whereby the inner end of said upper member may be placed in a vertical position against the link and rotated into its seated position, a tongue on said lower member arranged to enter said tongue-re1 ceiving recess to retain said members in seated relation, and means for securing said tongue in said recess, substantially as described.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
